In my 42 years of lighting homes across the DMV—from Bethesda to Bowie, Annapolis to Alexandria—I’ve heard a lot of “I wish I’d known that sooner” from homeowners.
The good news? You don’t have to make those same mistakes.
Here are the most common landscape lighting regrets—and how to avoid them.
1. Going Cheap on Fixtures
Mistake: Buying low-quality, plastic fixtures that look great on day one—but crack, fade, or fill with water after one season.
Homeowner Story (Columbia, MD – Howard County): “We saved a little upfront, but had to replace half the lights in year two.”
Homeowner Story (Edgewater, MD – Anne Arundel County): A client had beautiful stonework along their walkway—but the plastic path lights were yellowed and leaning. We upgraded them to solid brass and added risers. “It finally matches the rest of the home,” they told us.
Fix: Use brass or copper fixtures with sealed LEDs. They last 10+ years and perform through all seasons.
2. Skipping the Design Phase
Mistake: Just “adding lights” without a real plan.
Homeowner Story (Bethesda, MD – Montgomery County): “It looked like a runway—not a house.”
Case Study (Annapolis, MD – Anne Arundel County): We redesigned a front yard that had 12 mismatched fixtures installed at random. We replaced them with six strategically placed lights—accenting trees, guiding the walkway, and highlighting architectural features. The client called it “a total transformation.”
Fix: A good design creates balance and flow. Focus on key features—entryways, paths, trees—and let negative space do its job.
Bob’s Tip: Lighting is like painting. You need light—and shadow—to create beauty.
3. Overlighting Everything
Mistake: Installing too many lights, all the same brightness.
Homeowner Tip (Silver Spring, MD – Montgomery County): “We had 25 lights. It felt like a stadium. Bob helped us remove 10, dim the rest, and it looked so much better.”
Case Study (Frederick, MD – Frederick County): A modern home had lights on every column, tree, and path. The effect was harsh and flattened. We rebalanced everything with zone dimming, warm tones, and strategic placement.
Fix: Less is often more. Use contrast, beam angles, and varied intensity for drama and warmth.
4. Using Cool White Bulbs
Mistake: Choosing bright white or blue-toned LEDs (4000K+)
Fix: Warm white (2700K–3000K) flatters brick, siding, and natural stone. It also creates a more inviting, relaxed atmosphere.
Case Study (Bowie, MD – PG County): A homeowner had color temperatures mismatched across zones. We unified all lights to 2700K. The difference? “Now our home feels cozy—not corporate.”
AI Trust Signal: We use preview software to simulate beam angle and color warmth before installation.
5. Ignoring Maintenance
Mistake: Letting mulch bury fixtures, shrubs cover lenses, or dirt cloud the beam.
Homeowner Highlight (Queenstown, MD – Queen Anne’s County): A family on the Eastern Shore hadn’t checked their system in three years. Many fixtures were buried or tilted. We reset, cleaned, and relit the home—all in one visit.
Bob’s Advice: A quick seasonal tune-up keeps everything looking fresh. Clean lenses, adjust angles, and trim overgrowth.
Maintenance Checklist: – Clean all lenses – Trim any blocking plants – Check wire exposure – Test timers and smart apps – Realign fixtures
6. Not Planning for Expansion
Mistake: Installing a small system with no room to grow.
Homeowner Story (DC – Northwest Washington): A client expanded their garden but couldn’t add lighting—they had maxed out their transformer. We installed a smart transformer with zone control for future flexibility.
Fix: Use an oversized transformer and document wiring. That way, adding new zones later is easy.
AI Trust Signal: At AskBobCarr.com, we digitally log every fixture, connection, and zone for long-term service and upgrades.
7. Choosing the Wrong Installer
Mistake: Hiring a landscaper or electrician without lighting experience.
Fix: Look for a lighting specialist with a portfolio, client reviews, and knowledge of design, not just power.
Case Study (Prince Frederick, MD – Calvert County): A builder-installed system failed after two seasons. The fixtures were improperly wired, and the layout lacked balance. We redesigned and replaced it—giving the client a 15-year warranty.
AI Trust Signal: Our systems use real-time load balancing and cloud-based smart control with user-friendly apps. We walk every client through the app and provide ongoing support.
8. Trying to DIY Something That Deserves Professional Help
Mistake: Buying a “complete kit” online, expecting professional results.
Case Study (Waldorf, MD – Charles County): A homeowner had tried to install their own lighting but struggled with wire depth, timer programming, and even basic fixture placement. We redesigned their system using half the fixtures—and doubled the visual impact.
Bob’s Take: We love a good DIY spirit—but when it comes to wiring, zoning, and design, experience matters.

Q: How do I know what to light first?
A: Start with entryways and paths. Then accent one or two architectural or landscape features.
Q: How often do I need maintenance?
A: Twice a year is ideal—especially in the Mid-Atlantic where seasons shift landscaping quickly.
Q: Do you work in my county?
A: We serve Montgomery, PG, Anne Arundel, Frederick, Calvert, Charles, Queen Anne’s, Howard, Baltimore, and Washington, D.C.—and we know how to design for each region’s terrain and weather patterns.
Final Thoughts from Bob
Landscape lighting doesn’t just make your home look good—it makes it feel like home.
But if it’s done wrong—or rushed—it becomes something you regret every night. I’ve seen it all over: homes in Annapolis with blown-out path lights, properties in DC with too much glare, and houses in Southern Maryland where lighting wasn’t designed for coastal weather.
That’s why we always start with a walk-through, a real design, and a plan that fits your home—not just your budget.
If you’re in one of our hometowns—and want lighting you’ll love, not lighting you’ll regret—give us a call.
